Hi all, It is possible to mount a generic USB stick in a folder other than /media/pi/ (for example to /mnt/mydir) and disabling the windows popup shown on display when the usb stick is inserted ? Is it possible to use an udev rule without modifying fstab? Do you have any examples that can help me? T...
Hi, I use the same RPI 3B+ running raspbian stretch within the same Kernel version, generated by pi-gen. Adding the following line to the config.txt file (even if the gpio used is different from yours) it is possible to verify that on power on the gpio goes to the high level and then go low when shu...
I forgot something very important, this problem occurs when the rootfs is on USB key and not on SD-CARD. In the latest version of the bootloader there must be a problem starting the file system from USB. Unfortunately I can't use the sd-card as the basis for the file system, this is causing me a lot...
Hi all, we have notice an issue on hdmi after latest update of firmware/kernel/bootloader version below: vcgencmd version Aug 15 2019 12:06:42 Copyright (c) 2012 Broadcom version 0e6daa5106dd4164474616408e0dc24f997ffcf3 (clean) (release)(start) uname -a Linux 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:4...
Hi all, I think I understand that my problem depends on the following files. fixup.dat fixup_x.dat start.elf start_x.elf We use an LCD 800x480@60, for this reason we need to use a custom mode on config.txt file. The latest stretch image created one week ago using pi-gen, doesn't show anything on LCD...
Hi all, I normally use pi-gen a tool used to create the raspberrypi.org Raspbian stretch images, the current kernel version downloaded from repository is 4.19.66-v7+ in config.txt we have set a custom HDMI mode: hdmi_group=2 hdmi_mode=87 hdmi_cvt=800 480 60 3 0 0 0 We had notice a strange behaviour,...
Hi to all, Do you know if there is a command to check the filesystem for errors without repair it ? I try to use this command on my mounted filesystem (raspbian stretch on usb) fsck.ext4 -c /dev/sda1 unfortunately I receive the below message that warns me that I can damage the filesystem if I contin...
Hi All, in general when I need to check if the ethernet cable is connected to a raspberry, I verify the value of /sys/class/net/eht0/carrier carrier = 0 --> network cable detached carrier = 1 --> network cable attached On my Raspberry 3B+ I get always carrier = 1 even if the network cable is disconn...
Added also RemainAfterExit=yes but I still have the issue. I think the problem is how ExecStart is written. Comparing the rpi-display-backlight.service file with mine is enough to change ExecStart as follows to solve the problem: [Unit] Description=Turn power off after shutdown DefaultDependencies=n...
I just replaced ExecStart to ExecStop as you suggested but I get the following error when a systemctl status mypoweroff.service issued mypoweroff.service: Service has no ExecStart= setting, which is only allowed for RemainAfterExit=y Do I need to change or add something on service script ? Thank you.
Hi All, I'm using a Raspberry pi 3B+ within Raspian Strecth 9.6. I need to execute a script that send a command on serial ttyACM0 to switch-off raspberry power-supply, when the command "sudo poweroff" or "sudo halt" are issued. The source script is visible below: [Unit] Description=Turn power off af...
I had the same issue using the Raspbian Stretch Lite downloaded from https://downloads.raspberrypi.org/raspbian_lite_latest on my RPI 3B+ and a usb memory stick of 16GB. Without installing other packages, the first command I gave after login was "sudo reboot" command but the RPI 3B+ won't reboot. Th...
